TGMO has varied widely in its formulation over the years.
It is a Grp III oil but it looks like the add pack in the most recent formulation has reverted to a very high dose of moly along with very high VI, achieved only through the use of a very high VII content.
Nothing wrong with this oil, but maybe not the latest and greatest our current TGMO fanboi thinks it to be.
Personally, I prefer either M1 AFE or EP in this grade.
Both contain a nice percentage of PAO in their basestock blends and this shows for both in their class leading W and NOACK numbers.
Both of our 0W-20 cars will get AFE for their fall change, which will carry both through the coldest months.
I'm with you in that I don't want to do winter drains either.

Hard to tell of you're asking a serious questions her or trying to troll a TGMO vs the rest of the world oil Flamefest.
Pleasantly surprised BITOG has come with only common sense answers.
Yes your TGMO is plain old oil just like what is in the bottles at Walmart. No cross eyed unicorns were sacrificed to make it.
You can get TGMO at reasonable price but you really need to search for it on sale and usually Ebay or a toyota dealership.
Too much trouble when Walmart is right around the corner.
I've run TGMO, M1 AFE, PP, PUP, Magnetec and QSUD in my 2007 toyota tacoma and 14 sienna. never noticed a difference.

TGMO is fine from the specs we see on VOA's and once used with the reports on UOA's.
If you really want to know how it compares to other oils in your application, run comparative UOA's and then determine what's best for you.
TGMO is a perfectly fine oil to use long term though.

Do all the oil changes myself. When I reach 70 in three more years, I will stop.

If I use something like PP or M1 myself I'll save about half cost. So, in 2018, what's the TGMO formulation difference compared to PP or M1 or other name brands? The convenience of free coffee, tire rotation, a pastry, a checkup of major components, not getting covered in oil, finding a place in winter to change it that's warm, etc. make me feel like I want to be lazy. But changing oil also gives me a purpose in life. Makes me feel accomplished. Makes me feel manly. It's just the apartment lease says I can't on apartment property...but I'm sure I could snag a friend's driveway or a back alley or something.
You missed my latest review eleven days ago.
Is TGMO 0W-20 SN made in Heaven? Part II: high-moly GTL
TGMO 0W-20 © 2015 seems to be the best TGMO I've ever run, with the engine running extremely smoothly. I don't know if this will translate into a good UOA at the end of my OCI.
Caveat: Apparently there is now a © 2017 version and the formulation has changed again.

I-then suppose you are still working at almost 75? Sounds like you run your life without an age number.
I retired from my job at 66 - as I adopted an age number to do it.
It had absolutely nothing to do with how I feel. Neither does when I stop crawling under my vehicles.

Is this still the current stuff out there? : http://pqiadata.org/Toyota_0W20.html ? 787 ppm moly there, very similar to "Zepro Eco Medalist Advanced Moly 0w20" and Mazda Genuine Motor Oil 0w20 with gobs o' moly that protects the wear surfaces before the ZDDP tribofilm starts working when hot.
Other oils use far less moly, yet can cover the anti-wear hot/cold envelope by using esters & other means unknown.'
Bottom line: If an oil meets dexos1 Gen2, it performs well. Moly is interesting, but not the only way to do this.

LOL you always don't have a clue I retired at 62 and am doing well.
If it hadn't been for 9/11 I would have retired at 57.

hahaha to your no clue theory. I'm doing very well mentally and physically at 67. Likely better than you @ your 62.
You seem mentally incapable to grasp what I stated above. Seek a specialist soon sir.

As I said, I think the formulation has changed again, with a © 2017 version being available. The new formulation may not be ultra-high-viscosity-index (ultra-high-VI), may not have any GTL, and may not have high moly.
Two things:
(1) This oil is made by ExxonMobil in USA, not the Nippon Oil Co or Idemitsu in Japan like the TGMO SM, Mazda oil, or Zepro. The previous formulation of TGMO 0W-20 SN by ExxonMobil, like most USA-made oils, didn't have high moly.
(2) High moly (> 600 ppm) isn't for meeting any specs but for fuel economy. It's a Japanese-OEM thing, especially used for 0W-20 and 0W-16 (for which Japanese OEM's requested an exemption for 0W-20 and 0W-16 in TEOST 33C, as high moly can cause more deposits). Mg is for meeting the SN PLUS (and future SP) though.
From my experience TGMO has always been a great oil, including the previous SN formula without Mg and high moly. As I said, the © 2015 GTL/Mg/high-moly formula feels extremely smooth in my engine but I have no UOA yet.

Aye, but it still leverages the unique additive chemistry that combines Tinkerbell's earwax with Tom Thumb's belly button lint, which provides both incredibly linear viscometric characteristics and cold temperature performance. It's a proprietary WTL technology that XOM uses under license from Toyota and Disney

Updating the copyright date likely does not indicate the formula itself changed, as its only a labeling/legal thing.
Note the PQIA bottle (high moly) was purchased in 2018 but has the copyright 2015 on the front label. Again, just labeling updates.

Not true. High moly supports an AW cold tribofilm before ZDDP takes over under high heat and pressure. FM effects max out at under 100 ppm. This is why most oils don't go over 100 ppm of moly, since those smaller amounts max out the FM benefits at those low levels. (Mazda oil bottles state this directly on the label, and I read some technical articles years ago that said it.)
So why does Japanese oil use so much moly? They are concerned about the thinner (low HTHS) oils spending too much time in mixed and boundary lubrication regimes, and offer the extra moly to boost AW performance where pressures are too low to form ZDDP layers. Keep in mind Toyota has an eye on GF6 goals, with thinner and thinner oils that need better mixed-boundary performance. Other oil makers accomplish this with mostly esters sliming the surface, but lots of moly does it too, so they chose moly. (Think something similar to Castrol Magnatec's ester approach, but more of it as oil thins out even more in the future.)

No, MSDS data also shows that the © 2017 version is different -- low VI, different KV100, etc.
Your conclusions regarding moly are wrong. Friction-modifying effects do not saturate at 100 ppm. Where did you see this? Are you talking about trinuclear moly? There are many different moly types -- mononuclear, dinuclear, sulfur-free, etc.
If it's because Japanese are paranoid about wear in xW-20, then why do you see high moly only in 0w-20 but not in 5W-20, which has exactly the same viscosity?

I just noticed your ester comment as well, which is also very wrong. POE actually increases wear by competing for the metal surfaces with the AW/EP/FM additives. This is well-known. Higher valvetrain wear with some batches of Mobil 1 in the past may have been caused by POE. POE is for improving oxidation stability, not for antiwear. Do you really think that you can provide antiwear properties with an oil film without using a metal coating such as Zn or Mo?
Where is the reference that Magnatec is ester?
